uri-literals
Note: This is taken from the Chicken Wiki, where a more recent version could be available.
A reader extension providing URI literals of the form #<http://www.call-with-current-continuation.org/>.
Loading uri-literals also loads the uri egg and allows using convenient URI literals as follows:
#;1> (use uri-literals) #;2> #<http://www.call-with-current-continuation.org/> #<http://www.call-with-current-continuation.org/> #;3> ,x #<http://www.call-with-current-continuation.org/> (uri "http://www.call-with-current-continuation.org/") #;4> ,d #<http://www.call-with-current-continuation.org/> structure of type `uri': ... #;5> (car (uri-path #<mailto:foobar@example.org>)) "foobar@example.org"
Passing a -X uri-literals command-line option to csc allows you to conveniently make use of URI literals in your egg or compiled program without making the uri-literals egg a runtime dependency.
This egg installs a reader extension for #\< that reads a URI literal as described below in read-uri-literal. Additionally, a record printer is installed so that all URI objects are automatically printed using write-uri-literal.
Note that there are some caveats to using reader extensions when compiling; for more details, refer to the relevant FAQ entry.
[procedure] (read-uri-literal [PORT])
Reads a URI literal from PORT, which defaults to the value of (current-input-port). The literal is converted to a URI object as provided by the uri egg.
[procedure] (write-uri-literal URI [PORT])
Writes the URI object URI in #<uri> format to PORT, which defaults to the value of (current-output-port).
